What's at Stake

We can reduce our oil use. Scientists, engineers, and analysts have constructed a plan—Half the Oil—to cut U.S. oil use. Through smart policies and practices—including increased fuel efficiency, better biofuels, and advanced electric cars—we can realize the benefits of using less oil.

Progress is already being made. Fuel economy standards have made cars and trucks more efficient. Electric vehicles are becoming more widespread. And scientists are finding new ways to make our fuels cleaner—but more can be done.

It’s not just CO2: oil creates air pollution

Transportation is one of the U.S.’s largest sources of air pollution. In 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.

All this pollution has serious implications for public health, including increased incidences of respiratory ailments like asthma and bronchitis.

Regional Work

California has long been a clean vehicles leader. From forward-thinking electric vehicle policies, to pollution standards and clean fuel mandates, they’ve paved the way for both the federal government and other states. Still, more can be done, especially with freight.
